Abstract: Concrete is a complex heterogeneous material. Its internal structure controls its mechanical behavior through crack localization, branching, and coalescence. As a result, only models that represent its failure through ...

Abstract: Ancient Egyptian obelisks have existed for several millennia and have withstood numerous natural disasters. This study investigated the structural dynamic characteristics and the responses of several obelisks to earthquakes ...

Abstract: Building information modeling (BIM) is rapidly restructuring the construction industry, offering major enhancements in project outcomes. Although the emerging demands for BIM adoption are developing to become an industry ...

Abstract: Reinforced concrete (RC) shear walls are widely used as a seismic force–resisting system in nuclear facilities. Such walls are designed to be relatively thick with a few openings for radiation shielding as well as for blast ...

Abstract: Abrasive waterjets (AWJ) were used for the first time to commercially singulate electronic chips such as those used for flash memory cards found in digital cameras, cell phones, and universal ...

Abstract: Ultrahigh-pressure abrasive-waterjets (AWJs) are being developed as net shape and near-net-shape machining tools for hard-to-machine materials. These tools offer significant advantages over existing ...

Abstract: The general characteristics of surfaces machined with abrasive-waterjets (AWJs) are discussed in terms of surface texture and surface integrity. Data are presented from several studies involving ...

Abstract: An experimental and theoretical investigation was conducted to study the cutting of ductile metals with high-velocity abrasive jets. The investigation involved experimental cutting tests, visualization ...

Abstract: Abrasive-waterjets (AWJs) are formed by mixing high-pressure (up to 400 MPa) waterjets (0.1 to 1 mm in diameter) with abrasive particles in mixing tubes with typical 1/d ratios of 50 to 100. ...

Abstract: The sandstone rocks' integrity and consolidation may be highly affected by the type and the strength of the stimulation fluids. Strong acids such as HF/HCl impair the rock consolidation. The reduction in the sandstone rock ...
